I specifically got these to clean my plastic fermenter after I kegged the beer in it. Using these pads with some hot PBW makes my fermenter look brand new after a little scrubbing.

I can't think of anything better to scrub stainless steel with while still having a gentle touch on the metal.

These are the best for cleaning conicals! 5 Stars!

does not scratch the inside of the fermenters.

Great pads just don’t leave them in star San

I recommend this product but only for very smooth surfaces. Even then the pad leaves bits and pieces. It tends to fall apart a bit more than I would like. Perhaps its unavoidable to get this nice soft pad that doesn't scratch but also doesn't hold together as much as I'd like.

These are abrasive enough to remove the tough stains and grime but gentle enough that they won't scratch plastic or stainless surfaces. Only issue is that I need to keep ordering because my wife loves 'em for kitchen use too :)

These work very well on stainless steel fermentation tanks. Tough and abrasive enough to take off sediment but gentle on the finish. I recommend them highly. Now if they could come up with a pole attachment that could reach all the way down to the bottom of my tanks to scrub without having to get inside they would have an even bigger hitt.....

They work great for cleaning my large Speidels. They dry thoroughly when you are done so they don't smell funky after 1 or 2 uses.

I use these on my kettle and Speidel fermenter. They're tough enough to scrub off boiled-on scum from the kettle and gentle enough not to scratch the plastic.

I bought multiple packs of these. They are great for scrubbing without scratching. A must have for any brewer of any level.

Love these scrubbers. Don't know if it's recommended but I wash them in my laundry after using to make sure all the gunk comes out after cleaning.

I used these to clean my new Speidel fermenter. They worked great and there was no scratching.

These pads work great for cleaning w/o scratching

I like these scrubbers because they are hard on beer stone and debris but gentle on stainless. I use them all the time on my kettles and kegs. Combine with Barkeepers Friend and gets old kegs to a nice shine.

Reminds me of the scruby part on a sponge. The real benefit from these are that they come in a pack of 3 which in turn can be cut in half to make 6 and that like with the use of a sponge you're only using them for your brewing equipment and they dry fast so there's no mildew smells that can come from a sponge
